Students of ophthalmology are fortunate that this book has appeared in a new enlarged edition. The general plan and chapter headings remain the same as in earlier editions. The excellent bibliographies that follow each chapter have been brought up to date and constitute a valuable feature of the book. There have been extensive additions to those chapters dealing with subjects in which there has been much investigative work in the past six years. This particularly applies to the chapters on aqueous humor, intraocular pressure, and ocular motility. The author has the faculty of expressing himself clearly and succinctly so that even the most complicated matters appear simple. The format of the book is pleasing and the illustrations are good. This book should be required reading for all students of ophthalmology, clinicians, investigators, and residents.
